[MonoDevelop] Add Project Templates to MD

[Sergio A. Hernandez]

Hello,
How can I add my own project templates to MonoDevelop?
I create a .xpt.xml file and do the "mdtool setup pack" stuff and
looks like works well, but when I do "mdtool setup rep-build" I get
this error:
    MonoDevelop Add-In Setup Utility
    Checking directory: myaddins
    Addin configuration file not found in package.

By the way the local repository cann't be added I receive an error:
    The repository could not be registered.
I'll really appreciate your help.
I'm working on Kubuntu Feysty & Monodevelop 0.12
